Specflow.Storage

When using the Field,Value table syntax in specflow, we are not able to store certain values from a specfic TableRow. This package offers a TableParser and a simple key-value-storage to perform following actions:

Scenario: Store message parameters

Given the following message is generated

Field	Value
MessageType	TestMessage => $MessageType$
Destination	Destination1 =>$Destination$
IntValue	1=> $IntValue$

Then the storage has the following entries

Field	Value
MessageType	TestMessage
Destination	Destination1
IntValue	1

Based on the "=>$xyz$" syntax you are able to store the given value. We're also able to inject beforehand stored values (base on the "<=$xyz$" syntax):

When the following message is generated

Field	Value
MessageType	<= $MessageType$
Destination	<= $Destination$
IntValue	<=$IntValue$

Then the message contains

Field	Value
MessageType	TestMessage
Destination	Destination1
IntValue	1

Based on that this module offers two main objects:

• Storage, simple key-value-storage
• TableParser, entrypoint to inject or store data to or from a table.

Store data from a table

        [Given(@"blabla")]
        public void SomeGivenStep(Table table)
        {
            var tableParser = new TableParser();
            
            // Store values from table -> _storage is property of the Steps objects
            tableParser.StoreValues.From(table).In(_storage).Store();
            _message = new Message();
            foreach(var row in table.Rows)
            {
                if (!tableParser.RawHasTablePersistorOnlyData(row)) // Ignore rows that have only data for the TableParser
                {
                    _message.Parameters[row[ColumnNames.Field]] = row[ColumnNames.Value];
                }
            }         
        }

Inject data from a storage to a table

        [Then(@"blablabla")]
        public void SomeThanStep(Table table)
        {
            var tableParser = new TableParser();
            tableParser.InjectValues.From(_storage).To(table).Inject();
            
            // Move on here
        }
